[0028] First embodiment:
[0029] The first embodiment of the present application provides a scooter steering structure 10, which is used to achieve the steering of the scooter. Figure 1 , Figure 1 It is a schematic diagram of the structural disassembly of the scooter steering structure 10 according to the first embodiment of the present application.
[0030] like Figure 1 The scooter steering structure 10 includes an axle frame 11 , a rotating block 12 , a first elastic member 13 and a positioning assembly 14 .
[0031] The axle frame 11 is used to set the rotating wheel of the scooter, and the axle frame 11 can rotate around its steering axis S1. Specifically, the scooter steering structure 10 also includes a steering shaft S2, and the axis of the steering shaft S2 is the steering axis of the axle frame 11. The steering shaft S2 is passed through the axle frame 11 and fixedly set on the pedal of the scooter. Specifically, the pedal not only includes the part stepped on by the user, but also includes a head connected to the stepped part, and the steering shaft S2 can be fixedly set on the head.
[0032] Specifically, the axle frame 11 may be disposed at the front end of the scooter, and the axle frame 11 may include a first axle 111 and a second axle 112. The first axle 111 and the second axle 112 are disposed at two opposite sides of the axle frame 11 along the rotation axis L1 of the rotating wheel, and the first axle 111 and the second axle 112 are used to set the rotating wheel of the scooter. Optionally, the rotating wheel of the scooter may be rotatably disposed on the first axle 111 and the second axle 112. Of course, it may also be fixedly disposed on the first axle 111 and the second axle 112, in which case the first axle 111 and the second axle 112 may rotate relative to the axle frame 11. Of course, in other embodiments, the axle frame 11 may also be provided with only one rotating wheel.
[0033] It can be understood that when the rotating wheel rotates along the rotation axis L1, the scooter travels. When the axle frame 11 of the scooter turns, the rotating wheel of the scooter turns.
[0034] Specifically, the rotating block 12 and the shaft frame 11 can rotate coaxially around the steering axis S1. In some embodiments, the rotating block 12 can rotate around the steering axis S2. When the shaft frame 11 rotates, if the rotating block 12 does not rotate around the steering axis S2 or rotates inconsistently with the shaft frame 11, the shaft frame 11 can rotate relative to the rotating block 12.
[0035] More specifically, the shaft bracket 11 is provided with a mounting hole H, and the steering shaft S2 is provided in the mounting hole H. Optionally, the mounting hole H may be a through hole.
[0036] Optionally, a first bearing Q1 is disposed in the mounting hole H, and the steering shaft S2 is disposed in the bearing Q1. The provision of the first bearing Q1 can reduce the rotational friction coefficient between the shaft frame 11 and the steering shaft S2.
[0037] Optionally, a first limiting nut P1 is provided at one end of the steering shaft S2, and the first limiting nut P1 is screwed and arranged at one end of the steering shaft S2. A second limiting nut (not shown) is provided at the other end of the steering shaft S2, and the second limiting nut is screwed and arranged at the other end of the steering shaft S2. The first limiting nut P1 and the second limiting nut are used to prevent the axial shaft S from axially moving to ensure the stability of the steering structure 10. A washer R1 can be provided between the first bearing Q1 and the first limiting nut P1.
[0038] Specifically, the rotating block 12 can be in various shapes, such as disc, strip, block, etc. The rotating block 12 is provided with a through hole, the steering shaft S2 is passed through the through hole, and the rotating block 12 is spaced apart from the upper end surface of the shaft frame 11 .
[0039] Optionally, a first protrusion T1 is provided on one end face of the rotating block 12 away from the shaft frame 11, the through hole passes through the first protrusion T1, and the first protrusion T1 is provided in the second bearing Q2. The provision of the second bearing Q2 can reduce the rotational friction coefficient when the rotating block 12 rotates. The pedal may be provided with a mounting hole, and the second bearing Q2 may be fixedly provided in the mounting hole.
[0040] Optionally, a third bearing Q3 is provided at the portion of the steering shaft S2 close to the other end surface of the rotating block 12, the steering shaft S2 is inserted into the third bearing Q3, and the third bearing Q3 and the first bearing Q1 are respectively provided at both ends of the through hole H. By providing the third bearing Q3, the rotational friction coefficient between the shaft frame 11 and the steering shaft S2 is further reduced. A sleeve R2 is provided between the third bearing Q3 and the other end surface of the rotating block 12, the sleeve R2 is sleeved on one end of the steering shaft S2, and is provided in the through hole of the rotating block 12.
[0041] It is understandable that the shaft frame 11 can rotate around the steering axis S2, and the rotating block 12 can also rotate around the steering axis S2. When the shaft frame 11 rotates around the steering axis S2, and the rotating block 12 does not rotate around the steering axis S2, or rotates around the steering axis S2 but its rotation around the steering axis S2 is inconsistent with the rotation of the shaft frame 11 around the steering axis S2, the shaft frame 11 and the rotating block 12 rotate relative to each other. The inconsistent rotation refers to the inconsistent speed and / or direction of the rotation.
[0042] Optionally, a limiting groove N1 is provided on the end surface of the shaft frame 11 close to the rotating block 12, and a limiting portion N2 is provided on the side of the rotating block 12 close to the shaft frame. The limiting groove N1 is an arc-shaped groove, and the limiting portion N2 is a second protrusion provided on the rotating block 12. The number of limiting grooves N1 can be one or two, and the limiting portion N2 is correspondingly provided to one or two. When the number of limiting grooves N1 is two, the two limiting grooves N1 are symmetrically provided relative to the rotating axis S. The limiting portion N2 is provided in the limiting groove N1, and when the shaft frame 11 and the rotating block 12 rotate relative to each other, the limiting portion N2 slides in the limiting groove N1. By providing the limiting groove N1 and the limiting portion N2, the relative rotation angle of the shaft frame 11 and the rotating block 12 can only be within a specific range, thereby achieving the limitation of the relative rotation angle of the shaft frame 11 and the rotating block 12.
[0043] Among them, the first elastic member 13 is arranged between the shaft frame 11 and the rotating block 12. In one embodiment, one opposite end of the first elastic member 13 is connected to the rotating block 12, and the other opposite end is connected to the shaft frame 11. When the shaft frame 11 and the rotating block 12 rotate relative to each other, the first elastic member 13 undergoes elastic deformation. Specifically, one opposite end of the first elastic member 13 may be fixedly connected to the rotating block 12, and the other opposite end may be fixedly connected to the shaft frame 11. In another embodiment, a cavity for receiving the first elastic member 13 may be provided between the shaft frame 11 and the rotating block 12, and the first elastic member is installed in the cavity. When the shaft frame 11 and the rotating block 12 rotate relative to each other, the first elastic member 13 undergoes elastic deformation.
[0044] Optionally, the number of the first elastic member 13 may be one, two, three, etc. When the number of the first elastic member 13 is one, the steering shaft S2 may be inserted into the first elastic member 13 to make the overall structure compact and prevent the first elastic member 13 from deforming in its axial direction. When the number of the first elastic members 13 is two or more, part of the first elastic members 13 and the rest of the first elastic members 13 may be symmetrically arranged relative to the steering shaft S2, so that when the shaft frame 11 rotates, each part of the shaft frame 11 and the rotating block 12 is evenly stressed through the elastic member 13.
[0045] It is understandable that when the shaft frame 11 rotates around the steering axis S2 and the rotating block 12 cannot rotate around the steering axis S2, the first elastic member 13 disposed between the rotating block 12 and the shaft frame 11 will twist along its radial direction and then deform to generate torque. When the torque of the first elastic member 13 exists, it will hinder the shaft frame 11 and the rotating block 12 from rotating relative to each other. At this time, a large force is required for the shaft frame 11 to rotate. In addition, when the force applied to the pedal for the shaft frame 11 to rotate disappears, under the action of the torque of the first elastic member 13, the shaft frame 11 will return to its initial state before the rotation occurs.
[0046] The positioning assembly 14 includes a clamping member 141, which can rotate around its rotation axis L2, so that the clamping member 141 abuts against or disengages from abutment with one side of the rotating block 12. When the clamping member 141 abuts against one side of the rotating block 12, the rotating block 12 cannot rotate around the steering axis S2, and when the clamping member 141 disengages from abutment with one side of the rotating block 12, the rotating block 12 can rotate around the steering axis S2.
[0047] Specifically, the engaging member 141 can be disposed on a side of the rotating block 12 away from the shaft frame 11 and rotatably disposed at the front end of the scooter.
[0048] It is understandable that the engaging member 141 does not interfere with the rotating block 12 in the initial state, and the engaging member 141 does not affect the rotating block 12 from rotating around the steering axis S2. When the engaging member 141 rotates around its rotation axis L2 along the first rotation direction, the engaging member 141 interferes with one side of the rotating block 12. At this time, if the shaft frame 11 rotates around the steering axis S2, since the rotating block 12 cannot rotate around the steering axis S2, the first elastic member 13 will be elastically deformed. When the engaging member 141 rotates around its rotation axis L2 along the second rotation direction, the second rotation direction is opposite to the first rotation direction, and the engaging member 141 is out of conflict with the rotating block 12. At this time, if the shaft frame 11 rotates around the steering axis S2, the shaft frame 11 drives the rotating block 12 to rotate in the same direction through the elastic member 13, that is, the rotating block 12 cannot rotate relative to the shaft frame 11 or only rotates relatively to a small extent, and the first elastic member 13 does not deform or deforms slightly.
[0049] The present embodiment has at least the following beneficial effects: a first elastic member 13 is connected between the axle frame 11 and the rotating block 12 of the scooter steering structure 10 provided in the present embodiment, and both the axle frame 11 and the rotating block 12 can rotate around the steering axis S2. When the rotating block 12 cannot rotate around the steering axis S2, the first elastic member 13 undergoes elastic deformation to generate torque, and at this time a larger force is required to turn the axle frame 11. When the rotating block 12 can rotate around the steering axis S2, the rotating block 12 rotates in the same direction as the axle frame 11, and the first elastic member 13 does not deform or undergoes a smaller deformation, and at this time a smaller force can turn the axle frame 11. Further, the positioning assembly 14 is used to control whether the rotating block 12 can rotate around the steering axis S2, thereby adapting to the requirements of different forces required for the steering of the axle frame 11 in different scenarios.
[0050] Second embodiment:
[0051] This embodiment is described on the basis of the above first embodiment. Figure 2 Combined with Figure 1 , Figure 2 It is a schematic structural diagram of the rotating block 12 of the second embodiment of the present application.
[0052] Furthermore, the rotating block 12 includes a first main body portion 121 , a first arm 122 and a second arm 123 . The first arm 122 and the second arm 123 are respectively disposed on two opposite sides of the first main body portion 121 .
[0053] Specifically, the first main body 121 , the first support arm 122 and the second support arm 123 are integrally formed to ensure the structural stability of the rotating block 12 .
[0054] Further, the first elastic member 13 includes a first sub-elastic member 131 and a second sub-elastic member 132. One opposite end of the first sub-elastic member 131 is connected to the first arm 122, and the other opposite end of the first sub-elastic member 131 is connected to the first end of the shaft frame 11. One opposite end of the second sub-elastic member 132 is connected to the second arm 123, and the other opposite end of the second sub-elastic member 132 is connected to the second end of the shaft frame 11. Specifically, the first sub-elastic member 131 and the second sub-elastic member 132 can be the same elastic member.
[0055] Specifically, the first sub-elastic member 131 and the second sub-elastic member 132 may be torsion springs. A fixing groove G is provided on the end surface of the shaft frame 11 close to the rotating block 12, and the fixing groove G is used to fix the main part of the torsion spring to prevent the torsion spring from moving in its radial direction when the shaft frame 11 and the rotating block rotate relative to each other.
[0056] See also Figure 3 , Figure 3 It is a schematic diagram of the structural disassembly of the positioning component 14 of the first embodiment of the present application.
[0057] Furthermore, the engaging member 141 includes a second main body portion 1411 , a first clamping claw 1412 and a second clamping claw 1413 . The first clamping claw 1412 and the second clamping claw 1413 are arranged at a first side of the second main body portion 1411 with a gap therebetween.
[0058] Specifically, the second main body 1411 , the first claw 1412 , and the second claw 1413 are integrally formed to ensure the structural stability of the engaging member 14 .
[0059] Optionally, the first side of the second main body 1411 may also include only one claw. When one claw is provided, the engaging member 141 can only prevent the rotation of the rotating block 12 in one rotation direction. Of course, in other embodiments, the rotating block 12 may be provided with a slot, and the claw of the engaging member 141 may be engaged in the slot to prevent the rotating block 12 from rotating in any direction around the steering axis S2.
[0060] When the engaging member 141 rotates around the rotation axis L2, the first claw 1412 contacts the first arm 122, and the second claw 1413 contacts the second arm 123 at the same time. Or the first claw 1412 is out of contact with the first arm 122, and the second claw 1413 is out of contact with the second arm 123 at the same time. That is, when the engaging member 141 rotates around the rotation axis L2 in the first direction, the first claw 1412 contacts the first arm 122, and the second claw 1413 is also in contact with the second arm 123 at the same time. When the engaging member 141 rotates around the rotation axis L2 in the second direction, the second direction is opposite to the first direction, the first claw 1412 is out of contact with the first arm 122, and the second claw 1413 is also out of contact with the second arm 123 at the same time.
[0061] Furthermore, the positioning assembly 14 also includes a positioning plate, which is arranged on one side of the shaft frame 11 and located on at least one side of the second main body 1411. The second main body 1411 can rotate relative to the positioning plate, and the positioning plate is provided with at least a first positioning groove M1 and a second positioning groove M2.
[0062] Specifically, the positioning plate and the second main body 1411 are both provided with through holes, the engaging member rotation axis Y is passed through the through holes, the positioning plate and the engaging member rotation axis Y are fixedly connected, and the second main body 1411 can rotate around the engaging member rotation axis Y.
[0063] Optionally, the positioning plate can be arranged in a circular shape, and the first positioning groove M1 and the second positioning groove M2 are arranged at intervals along the circumference of the positioning plate at the edge of the positioning plate. There is a predetermined angle between the first positioning groove M1 and the second positioning groove M2, and the predetermined angle is greater than 30 degrees and less than 90 degrees, preferably greater than 45 degrees and less than 60 degrees.
[0064] Optionally, the positioning plate includes an identical first positioning plate 1421 and a second positioning plate 1422, wherein the first positioning plate 1421 is disposed on one opposite side of the second main body portion 1411, and the second positioning plate 1422 is disposed on the other opposite side of the second main body portion 1411. Specifically, a line connecting the first positioning groove M1 of the first positioning plate 1421 and the first positioning groove M1 of the second positioning plate 1422 is on the same straight line, and a line connecting the second positioning groove M2 of the first positioning plate 1421 and the second positioning groove M2 of the second positioning plate 1422 is on the same straight line.
[0065] The positioning assembly 14 further includes a positioning rod 143 , which is movably disposed on the engaging member 141 for engaging with the first positioning groove M1 or the second positioning groove M2 .
[0066] Further, the engaging member 141 further includes a limiting portion 1414, which is disposed on the second side of the second main body portion 1411, and the first side of the second main body portion 1411 and the second side of the second main body portion 1411 are two opposite sides of the second main body portion 1411. Specifically, the limiting portion 1414 is provided with a limiting slide groove X, and the limiting slide groove X is extended along the length direction of the limiting portion 1414, and the positioning rod 143 is disposed in the limiting slide groove X, that is, the positioning rod 143 slides in the limiting slide groove X.
[0067] When the positioning rod 143 is engaged in the first positioning groove M1 , the engaging member 141 contacts one side of the rotating block 12 . When the positioning rod 143 is engaged in the second positioning groove M2 , the engaging member 141 is out of contact with one side of the rotating block 12 .
[0068] It is understandable that when the engaging member 141 rotates to contact one side of the rotating block 12, the positioning rod 143 provided in the limiting portion 1414 of the engaging member 141 can be engaged with the first positioning groove M1 to limit the engaging member 141, and the engaging member 141 cannot rotate at this time. When the positioning rod 143 is disengaged from the first positioning groove M1, the engaging member 141 can rotate to disengage from contact with one side of the rotating block 12, and the positioning rod 143 can be engaged with the second positioning groove M2, and the engaging member 141 cannot rotate at this time.
[0069] Furthermore, the positioning assembly 14 also includes a third elastic member 144, one end of the third elastic member 144 is connected to the first side of the positioning rod 143, the first side of the positioning rod 143 is the side of the positioning rod 142 away from the second main body portion 1411, and the other end of the third elastic member 144 is connected to one end of the limiting portion 1414 away from the second main body portion 1411.
[0070] The third elastic member 144 is a compression spring. When the positioning rod 143 is engaged with the first positioning groove M1 or the second positioning groove M2, the third elastic member 144 is in a normal state. If the positioning rod 143 moves in the limiting slide groove X and has a tendency to disengage from the first positioning groove M1 or the second positioning groove M2, the third elastic member will press the positioning rod 143 to prevent the positioning rod 143 from disengaging from the first positioning groove M1 or the second positioning groove M2. Therefore, unless the positioning rod 143 is manually disengaged from the first positioning groove M1 or the second positioning groove M2, it is difficult for the positioning rod 143 to disengage from the first positioning groove M1 or the second positioning groove M2.
[0071] For example, when the positioning rod 143 is disengaged from the first positioning slot M1 to engage with the second positioning slot M2, when the positioning rod 143 needs to move to disengage from the first positioning slot M1, the elastic force of the third elastic member 144 needs to be overcome. At this time, the third spring 144 is in a compressed state, and the third elastic member 144 exerts a force on the positioning rod 143 in a direction opposite to the moving direction of the positioning rod 143. When the positioning rod 143 needs to move to engage with the second positioning slot M2, the third elastic member 144 will return to normal and prevent the positioning rod 144 from disengaging from the second positioning slot M2.
[0072] See also Figure 4 , Figure 4 Schematic diagram of the arrangement of the second elastic member 145 of the positioning assembly 14 of the second embodiment of the present application.
[0073] In other embodiments, the positioning assembly 14 includes a second elastic member 145, one end of the second elastic member 145 abuts against the second side of the second main body 1411, and the other end of the second elastic member is connected to the second side of the positioning rod 143. Specifically, one end of the second elastic member 145 can be fixedly connected to the rotation axis C of the second main body 1411, and the other end can be fixedly connected to a side of the positioning rod 143 close to the engaging groove. There can be two second elastic members 145, which are respectively disposed on both sides of the second main body 1411.
[0074] Among them, the second elastic member 145 is a tension spring, and when the positioning rod 143 is engaged with the first positioning groove M1 or the second positioning groove M2, the second elastic member 145 is in a normal state. At this time, if the positioning rod 143 needs to be moved to disengage from the first positioning groove M1 or the second positioning groove M2, it is necessary to overcome the elastic force of the second elastic member, that is, it is necessary to stretch the second spring 145, and at this time the second spring 145 is in a stretched state. Further, when it is necessary to engage the positioning rod 143 with the first positioning groove M1 or the second positioning groove M2, it is necessary to release the pulling of the second spring 145 so that the second spring 145 is in a normal state. At this time, if the positioning rod 143 is to be disengaged from the first positioning groove M1 or the second positioning groove M2, it is necessary to overcome the elastic force of the second spring 145, so that the second spring 145 can make the positioning rod 143 firmly engaged with the first positioning groove M1 or the second positioning groove M2.
[0075] When the positioning rod 143 is engaged with the first positioning groove M1 or the second positioning groove M2 , the third elastic member 144 is in a stretched state.
[0076] See also Figure 5 , Figure 5 It is a cross-sectional view of the scooter steering structure 10 according to the second embodiment of the present application.
[0077] like Figure 5 In some embodiments, a first inclination angle W is formed between the rotation axis D of the rotation shaft S and the straight line C. The straight line C is perpendicular to the direction of the pedal plane of the pedal N.
[0078] Specifically, the first inclination angle is greater than 30 degrees and less than 90 degrees. Preferably, the first inclination angle is 19 degrees.
[0079] It can be understood that by setting the rotation axis S to have a first inclination angle W relative to the pedal plane, the shaft bracket 11 can be rotated by tilting the center of gravity on both sides of the pedal.
[0080] For example, when the user places his / her own center of gravity on the first side of the pedal, the axle frame 11 rotates toward the first side to enable the scooter to turn toward the first side. When the user places his / her own center of gravity on the second side of the pedal, the second side may be a side opposite to the first side, and the axle frame 11 rotates toward the second side to enable the scooter to turn toward the second side. The first side may be the left side of the scooter's forward direction, and the second side may be the right side of the scooter's forward direction.
[0081] See also Figure 6 as well as Figure 7 , Figure 6 is a schematic diagram of a combined structure of the steering structure 10 of the second embodiment of the present application, Figure 7 It is another schematic diagram of the combined structure of the steering structure 10 of the second embodiment of the present application.
[0082] The steering structure 10 further includes a sleeve 15 sleeved on the limiting portion 1414 , and the positioning rod 143 is moved out of the first positioning groove M1 or the second positioning groove M2 by moving the sleeve 15 along the length extension direction of the sleeve 15 .
[0083] Furthermore, rotating wheels Z are respectively provided on both sides of the shaft frame 11 . Figure 6 The positioning rod 143 of the positioning assembly 14 is engaged with the first positioning groove M1. At this time, the first claw 1412 and the second claw 1413 of the engaging member 141 are in conflict with the rotating block 12. At this time, if the shaft frame 11 rotates, the rotating block 12 cannot rotate around the steering axis S2.
[0084] In one application scenario, after the turning force of the scooter disappears, if the scooter needs to automatically restore its direction, the positioning assembly 14 can be adjusted as follows: Figure 6 Status shown.
[0085] Figure 6 The positioning rod 143 of the positioning assembly 14 is engaged with the second positioning groove M2. At this time, the first claw 1411 and the second claw 1412 of the engaging member 141 are disengaged from the rotating block 12. At this time, when the shaft frame 11 rotates, the rotating block 12 can rotate around the steering axis S2.
[0086] In one application scenario, the user pulls the scooter by means of a pull rope attached to the shaft frame 11 to make it move. When the pull rope is perpendicular to the shaft frame 11, the scooter can be moved in a straight line by pulling the pull rope. When the user changes the pulling direction so that the pull rope and the shaft frame 11 are not perpendicular to each other, it is necessary to be able to achieve the steering of the scooter with a smaller force. At this time, the positioning assembly 14 can be adjusted as follows: Figure 6At this time, the force of the pull rope is not enough to rotate the shaft frame 11 and the rotating block 12, but it is enough to rotate the shaft frame 11 of the scooter, thereby driving the rotating wheel Z of the scooter to turn to the same side as the pulling direction of the pull rope, thereby realizing the steering of the scooter.
[0087] In another application scenario, the user does not stand on the pedals but pushes the scooter forward by the handle bar. Preferably, the handle bar is in a folded and tilted state to facilitate the user to push the scooter. In this case, a smaller force is required to turn the scooter, which can adjust the positioning assembly 14 as follows: Figure 7 At this time, the force applied by the user to the handle bar is not enough to cause the rotation between the axle frame 11 and the rotating block 12, but is enough to cause the axle frame 11 of the scooter to rotate, thereby driving the rotating wheel Z of the scooter to turn, thereby realizing the steering of the scooter.
[0088] This embodiment at least has the following beneficial effects: on the basis of the above-mentioned first embodiment, this embodiment ensures that the engaging member 141 can prevent the rotating block 12 from rotating in any direction through two clamping claws. Moreover, the setting of two torsion springs achieves a stronger restoring ability of the shaft frame 11. Moreover, the positioning rod 143 slides in the positioning slot X, and can be engaged with the positioning plate through the first positioning slot M1 and the second positioning slot M2, so that the engaging member 141 and the rotating block can maintain a stable state of conflict, or be out of the state of conflict. Moreover, the positioning rod 143 can slide in the positioning slot X through the third elastic member 144, thereby realizing the rapid switching positioning between the positioning rod 143 and the first positioning slot M1 and the second positioning slot M2.
[0089] Third embodiment:
[0090] This embodiment provides a scooter 20, see Figure 8 as well as Fig. 9 , Figure 8 is a schematic diagram of a structural disassembly of a scooter 20 according to a third embodiment of the present application. Fig. 9 It is a schematic diagram of a structural assembly of a scooter 20 according to the third embodiment of the present application.
[0091] like Figure 8 As shown, the scooter 20 includes a handle bar 21, and the handle bar 21 includes a handle 211 and a support bar 212. The scooter also includes a pedal N, a lower housing 23, and rotating wheels, and the rotating wheels include a rear wheel 24 and a front wheel 25. The lower housing 23 is arranged on a side of the pedal N away from the handle bar 21, the rear wheel 24 is arranged on a side of the lower housing 23 away from the pedal N, and the front wheel 25 is arranged on two opposite sides of the front end of the pedal N.
[0092] The scooter 20 further comprises the scooter steering structure 10 of any one of the above-mentioned embodiments, wherein the end of the support rod 212 away from the handle 211 is fixedly connected to the engaging member 141 of the positioning assembly 14 of the scooter steering structure 10. When the engaging member 141 rotates around its rotation axis L2, the support rod 212 also rotates around the rotation axis L2 at the same time. Since the positioning rod 143 of the positioning assembly 14 can be engaged with the first positioning groove M1 or the second positioning groove M2 when the engaging member 141 rotates, the support rod 212 has a first state corresponding to the first positioning groove M1 and a second state corresponding to the second positioning groove. In this embodiment, the notch of the first positioning groove M1 is arranged in a substantially vertical upward direction, and the notch of the second positioning groove M2 is inclined toward the upper side of the pedal N, so the first state of the support rod 212 is a vertical state, and the second state is an inclined state. When the support rod 212 is in a vertical state, the engaging member 141 is in conflict with the rotating block 12, and the rotating block 12 cannot rotate around the steering axis of the axle frame 11. Therefore, when the scooter turns, the rotating block 12 and the axle frame 11 rotate relative to each other. Due to the action of the first elastic member 13 provided between the axle frame 11 and the rotating block 12, the scooter has an automatic self-centering function, but steering requires a large force. At this time, the scooter can be driven to turn by the center of gravity tilting steering structure. When the support rod 212 is in a tilted state, the engaging member 141 is out of conflict with the rotating block 12, and the rotating block 12 can rotate around the steering axis of the axle frame 11. Since the rotating block 12 does not need to overcome the force of the first elastic member 13 to rotate around the steering axis, the scooter can be driven to turn in a more labor-saving manner, for example, the user can stand on the ground and push the support rod 212 to turn.
[0093] Preferably, the support rod 212 includes a telescopic structure, and the support rod 212 can change the length of the support rod 212 through the telescopic structure, thereby realizing the height of the handle 211 relative to the pedal N. In one application scenario, if the user is tall, the support rod 212 can be adjusted to increase the height of the handle 211 to improve the user's comfort. In another application scenario, if the user is short, the support rod 212 can be adjusted to reduce the height of the handle 211 to improve the user's comfort.
[0094] The present embodiment has at least the following beneficial effects: the scooter 20 provided in the present embodiment has the scooter steering structure 10 described in any of the above embodiments, so that when the axle frame 11 rotates, the positioning assembly 14 can be used to control whether the rotating block 12 rotates relative to it, thereby adapting to the requirements of different magnitudes of force required for the steering of the axle frame 11 in different scenarios.
[0095] It is worth noting that the above embodiments or the technical features described in the above embodiments can be combined as needed to form other embodiments if there is no conflict.
[0096] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
